Abstract: 1,052,275. Dividing by a single blade. LODGE & SHIPLEY CO. May 20, 1963 [May 21, 1962], No. 20011/63. Heading B3W. In a method of removing surface metal from a blank, a freely-rotatable roller having a peripheral conical surface engages the blank and exerts a force in a direction normal to the thickness of said blank surface, causing metal to shear in the direction of application of the force and also to flow away from the blank in a direction transverse to the direction of the force application. The roller R has a conical workengaging surface 1 and an adjacent coaxial conical surface 2. The blank 6 is supported by known means and driven about the axis 7 and the roller R is applied to the blank so that the surface " h " makes an angle of between - 2 and +10 degrees with the blank surface. There is a clearance of ¢ to 2¢ degrees between the surface 10 to be sheared and the conical surface 2. The blank is rotated and the roller R is moved parallel to the axis of the blank so that the point of contact follows a helical path around the blank and metal 20 is progressively sheared from the periphery of the blank. The Specification also describes the application of the method to removing the end surface from a cylindrical blank, from the inside of a tubular blank and from a plane surface.

Abstract: 1,226,856. Power-tongs. BYRON JACKSON Inc. 6 Sept., 1968 [17 Oct., 1967], No. 42574/68. Heading B3N. A power tong assembly comprises a pipegripping head 1, Figs. 2, 3a, 3b, in which a gear 11 is mounted to be driven in either direction through gearing, at a high speed and low torque, by a fluid pressure motor M1, or at a low speed and high torque by simultaneous operation of fluid-pressure motors M1 M2. Ring 11 has a cam path 18, 19, Fig. 4, which co-operate with rollers 44 carried by spring-urged jaws 40 slidably mounted in an inner ring assembly 20, Fig. 3a, so that rotation of gear 11 about assembly 20 will cause radial movement of jaws 40. Brake means 51, 52 are provided for applying a drag to assembly 20. After operating on the pipe or rod, the jaws are released by reversing the direction of rotation of the gear 11, so that rollers 44 move on to the regions 18 of the cam path. However, in order to prevent further relative rotation between gear 11 and assembly 20, and consequent further gripping of the jaws, an angularly adjustable ring 63, secured to gear 11, Fig. 6, locks the gear to assembly 20 by rollers 72, 75, and floating wedges 74. Motor M2, Fig. 3b, drives a ring gear 90 through a double-acting, self-energizing, over running clutch C, and a brake drum 104 is provided which assists the clutching operation. The valves V1, V2, Fig. 12, for controlling the supply of fluid to motors M1, M2 are controlled by levers 135 which actuate linkages 133, 134, through a rocker shaft located in a hollow shaft 122.

Abstract: 1,227,368. Automatic speed control. LENINGRADSKY METALLICHESKY ZAVOD IMENI XXII SIEZDA KPSS. Aug. 8, 1968, No. 37874/68. Heading G3R. The flow of liquid through a turbine 1 and therefore its speed is controlled by a proportional and integral feedback loop comprising a tachogenerator 2; a magnetic amplifier 33-34-55 and a hydromechanical actuator 17, the loop including a T- network 40-45 of the form shown. The speed of the turbine is measured by the tachogenerator 2, 5, 6 whose variable frequency output is applied to a tuned circuit 3, 4 giving an output in a transformer 8 when the speed deviates from a predetermined value. The output of transformer 8 is applied through a transformer 27 to a phase sensitive detector 31 the output of which is fed to the magnetic amplifier 33, 34, 35, which feeds the actuator 17. The output of the tachogenerator is also applied to a transformer 14 which provides power to the magnetic amplifier and to two potentiometers 20, 25 whose position is controlled by the actuator 17. The output of potentiometer 20 is added through transformer 21 with a speed setting value from transformer 9 to the output of transformer 8 applied to the phase detector. The output of potentiometer 35 is applied through transformer 36 and a bridge rectifier 39 to the input of the T-network 40-45. The output of the T-network is applied through a variable capacitance 46-48 to the input of the magnetic amplifier. The turbine speed is set by potentiometer 11 (driven by a motor 13), the minimum setting being set by a potentiometer 12. The inclusion of the T-network is stated to permit independant adjustment of the time constant and feedback factor of the loop while keeping their product constant. The variable capacitance 46-48 permits altering the time constant keeping the feedback factor constant; the additional capacitors 47,48 are precharged from rectifier 39 to avoid upsetting the system when changing capacitance.

Abstract: 1,228,433. Semi-conductor devices. SIEMENS A.G. 5 April, 1968 [8 April, 1967; 21 July, 1967], No. 16652/68. Heading H1K. A conductor assembly is formed from sheet metal so that the conductors to be attached to a monocrystalline pn - junction - containing element are formed with lugs which when the element is placed between them grip the element to hold it during the soldering process. A conductor assembly for two rectifiers is shown in Fig. 3. After the elements 1 have been placed in the positions indicated and soldered, insulation may be cast or moulded around the assembly leaving the conductor ends exposed, and the linking web 4 trimmed away. In another assembly (Fig. 4, not shown) five conductors (like 2, 34) are used to hold the four elements of a full wave rectifier. On the side of the assembly opposite to the linking web there is a permanent connecting strap between the outermost conductors so that only four connections need be made to the bridge. Such an assembly may be placed in a plastic housing having slots moulded in the inside of its side walls to receive the outer conductors of the bridge. The housing may be filled with a thermoplastic or thermosetting resin with a silicone content to make it water-impenetrable. The assembly shown in Fig. 7 is also formed from a plane sheet but the central conductor 2 is bent twice to bring its single lugs 21 over the single lugs 30 of the outer conductors 31. Insertion of the semi-conductor elements displaces the conductors from their equilibrium position so that the lugs are resiliently held against the elements. In another variant, Fig. 10, there is little separation between the ends of facing lugs 21, 30 which are bent slightly from the plane containing their conductors 2, 3. The gap is less than the thickness of the semi-conductor elements which when inserted is thus held at an angle between the lugs and cannot drop out. The Specification also describes an assembly for holding and making contact to a three electrode device, a thyristor.
